Mitrovic looked a couple inches offside, Salah looked a couple feet off, but didn’t ever see a good replay to get a good gauge on where the defender closest to the camera view was.
I did think the official should have called back the free kick that Allison toon though since it was taken well back from where the offside was in order to take advantage of Fulham not being ready. If it’s taken slowly and with no pressure, those 10 yards are usually let go, but when it’s done fast to catch a team, officials are usually stricter about it being taken from the right spot.
Either way, Liverpool scored a second goal that didn’t have anything to do with Fulham pressing, and I think Fulham easily could have got a red, so it’s hard to think they got screwed out of a point.
